*****************************************************SELECT APPLICABLE MOUNTING HEIGHT. GENERALLY 72 INCHES WILL BE USED; HOWEVER, 48 INCHES SHALL BE USED WHERE HANDICAPPED ACCESS IS REQUIRED (E.G., TO RESET CIRCUIT BREAKERS IN A RESIDENCE).**********************************************************************************************************Mounting Height: Unless otherwise indicated, mount cabinets so the top is [48] [72] inches above the floor or grade if no floor exists at cabinet location.**************************************************************************************************************1991 ADA Accessibility Guidelinesbook from the U.S. Architectural & Tranportation Barriers Compliance Board.This department has been renamed.I think you are really asking for the minimum and maximum mounting heights for equipment to be accessed by someone in a wheelchair. These dimension depend on if the person can approach the device from the front or from the side while in the chair. From the guidelines: in a chair with front approach: 15" minimum, 48" maximum; in a chair with side approach: 9" minimum, 54" maximum. But please check these out.
